A. B. MUELLER CYLINDER PROTECTOR original Filed July 5' 1923 R \zfimfi WITNESSES INVENTOR /1 W i BMZLQZZG 71 ATTORNEYS i be seen that the improved protector forms an efficient means for preventing objects from lodging on the cups and interfering with the operation of the same. The inventive idea involved in this application may be carried out in shallow-or deep well cylinders of any size, construction or arrangement. 7

In operation, various types of screens, and strainers may be employed to combat sand, clay and rust and to protect the parts of the working barrel and the cup leathers The openings in the various strainers may be either large or small according to the formation within which the same are located and the gravity of the fluid pumped.

The foregoing illustrates that this invention is capable of a wide variety of mechanical expressions and it is therefore to be un derstood that such minor changes in arrangement and construction of parts may be made as will remain within the spirit of the invention and the scope of what is claimed.

I claim:

1. A protector for well equipment com prising an outside protector tube, the ends of which are provided with reducers, a perforated strainer member arranged within the outside protector tube and having threaded connection with one of said reducers, a. gland having connection with said tube and adapted for the reception of the sucker rod, and a nipple connected to one of said reducers and adapted for connecting the outside protector tube to the upper portion of a working barrel.

2. A protector for well equipment comprising an outside protector tube, the ends of which are provided with reducers, a perr'orated strainer member arranged within the outside protector and having threaded connection with one of said reducers, a gland having connection with said tube and adapted for the reception of a sucker rod, and a nipple connected to one of said reducers and adapted for connecting the out side protector tube to the upper portion of a working barrel, said tube being provided with a series of diagonal incisions.
